Abstract: A focus adjustment apparatus comprises a detection unit that detects one or more main subject candidates for a main subject from image signals based on a predetermined first condition, a selection unit that selects the main subject from the one or more main subject candidates, an acquisition unit that acquires operation information of an operation unit for moving a position of a focus lens, and a focus adjustment unit that controls the focus lens so as to focus on the selected main subject in a case where an autofocus mode is set and the operation unit is not operated. In a case where the operation unit is operated, the selection unit selects the main subject based on an in-focus position of the focus lens and fixes the selected main subject.

Abstract: An information processing apparatus comprises a first acquisition unit that acquires a captured image obtained by capturing an image of a chart for calibration, a second acquisition unit that acquires a reference image which is an image of the chart that serves as a reference, a third acquisition unit that acquires information on distortion aberration of a lens used to capture the captured image, a first generation unit that generates a pseudo image which is an image obtained by reflecting the distortion aberration in the reference image, based on the reference image and the information on distortion aberration, and a second generation unit that generates a composite image obtained by compositing the captured image and the pseudo image.

Abstract: A 3D data generation apparatus includes: an acquisition unit that acquires a plurality of images and distance information that corresponds to distances in a depth direction to an object in the plurality of images; a determination unit that determines a layout for presenting the plurality of images as a piece of 3D data; and a combining unit that combines the plurality of images in accordance with the layout determined by the determination unit. The determination unit converts, for distance information of each image in the 3D data, the distance information of each of the plurality of images based on a predetermined criterion.
